## Long description

Diam S3 core drill bit with a 112 mm cutting diameter and a 450 mm overall length, designed for core drilling in masonry and concrete. The bit has a 1 1/4" connection size for use with compatible rotary or diamond core drilling rigs. It is intended to produce accurate circular holes for plumbing, electrical and installation work where a clean, consistent bore is required.
Advantages
The tool provides a large 112 mm cutting diameter that enables efficient removal of material for service openings and through-holes. Its 450 mm length allows drilling through moderately thick walls and slabs while maintaining stability and control. The 1 1/4" connection ensures compatibility with a wide range of core drilling adaptors and rigs. The construction and cutting geometry are optimized for clean cores and reduced breakout on exit, improving the quality of holes in concrete and masonry.
Suitable for
Drilling circular holes for plumbing installations
Creating service penetrations for electrical conduits and cables
Opening passages for HVAC and ventilation ducts
On-site core sampling and small-scale concrete removal
Key specifications
Cutting diameter: 112 mm
Overall length: 450 mm
Connection size: 1 1/4" (male thread)
Material compatibility: concrete, masonry and similar mineral substrates
Typical application: wet or dry core drilling with appropriate rig and coolant
How to use
Mount the core bit on a compatible drilling rig or adapter with a 1 1/4" connection and secure it according to the rig manufacturer’s instructions. Position the rig perpendicular to the surface and start drilling at low speed to establish a guide groove, then increase speed and apply steady, even pressure. For best results in concrete and masonry, use appropriate coolant or water feed if the rig supports wet drilling; for dry drilling follow tool and rig recommendations for dust extraction. Withdraw the bit occasionally to clear cuttings and prevent overheating. After reaching the required depth, retract the core bit slowly to remove the core and inspect the hole for breakouts or irregularities.
Usage recommendations
Use with a stable drilling rig and suitable mounting adaptors. For prolonged life and cleaner holes, prefer wet drilling with adequate water supply and a vacuum dust extraction system when dry cutting. Match drilling speed and feed pressure to substrate hardness and follow all safety guidelines, including eye, ear and respiratory protection.
